Application December 31, 1954, Serial No. 479,010

1 Claim. (Cl. 160-104) My invention relates to an improved type of window guard which serves the purpose of providing a positive protection against burglars and also to protect those inside, such as small children, from falling out of the window when it is open.

It is a further object of my invention to provide such window guard which is easily removable when unlocked but which will be extremely difficult to remove when locked.

it is a further object of my invention to provide such a window guard, especially for use when a window is wide open. This feature allows the occupant to leave windows wide open when asleep in warm weather with assurance of protection from intruders.

I attain these objects with the device illustrated in the accompanying drawings in which Fig. l is a top View of my device installed in a double-hung window frame;

Fig. 2 is a plan view of my device;

Fig. 3 is a detail of the upper left-hand portion of my device as shown in Fig. 2 with portions cut away;

Fig. 4 is a cross-section along the lines 4-4 in Fig. 3;

Fig. 5 is a cross-section of a portion of my device along the lines 55 in Fig. 2;

Fig. 6 is a detail of the lower left-hand portion of my device as shown in Fig. 2 with portions cut away to show the details of inside construction;

Fig. 7 is a plan view of the link portion of my device;

Fig. 8 is a cross-section along the lines 8-8 shown in Fig. 7;

Fig. 9 is a cross-section along the lines 8-8 shown in Fig. 7; and

Fig. 10 is a perspective view of the link portion of my device with the cut-out portion of the link shown in an extended position.

Similar numerals refer to similar parts throughout the several views.

The supporting frame of my device comprises channelshaped side guides 10 and 11, which are fastened by means of screws 42 to the sides of the window frame 12, and a base portion 13 which is fastened by means of screws 42 to the window sill 14. The entire device is constructed of steel or similar durable metal. Into this supporting frame, I insert a grill 15 which is comprised of a left-hand portion 15a and a right-hand portion 15b. The grill 15 is divided into four sections 16, 17, 18, 19, and two side pieces 20, 21. The left hand of the grill 15a comprises a side piece which is hinged to a section 16 which is, in turn, hinged to section 17. The right-hand portion of the grill 15b is comprised of the side piece 21 which is hinged to section 19, which is, in turn, hinged to section 18. The hinges used are similar and are designated by the numeral 22. It is thus apparent that the grill 15 may be folded on the hinges 22 by halves into quarter sections for installation and removal.

Each of the quarter sections 16, 17, 18 and 19 are provided with lugs 23 at the lower portions thereof which are adapted to fit into holes 24 provided at proper internite States Pat 0 F Patented Dec. 18, 1956 ice vals in the base portion 13. Each of the side pieces 20 and 21 has apertures 25. Each of the channel-shaped side guides 10 and 11 has apertures 26 of a similar diameter to the aperture 25 and I have provided pegs 27 to fit through the mentioned apertures 25 and 26.

I have also provided top frame members 23 and 29 which are channel supports to strengthen the rigidity of the grill 15 when it is in position. The top frame members 28 and 29 fit over grill portions 15a and 15b, respectively, and slide within the channel side members 10 and 11 on each side. The upper ends of the channel side members 10 and 11 have solid end portions 10a and 11a and the outer ends of the top frame members 28 and 29 have solid blocks of steel 28a and 29a, respectively, on their upper end portions so that the blocks 28a and 29a will fit into the side member ends 10a and 11a, respectively. The blocks 28a and 29a are rigidly fastened to the top frame members 28 and 29 by means of rivets or welding.

The locking feature of my device comprises a metallic link 30 constructed out of metal having a window frame receiving portion 31 and connecting portion 32 and a grillreceiving portion 33. A strip of metal 34 is provided to form the rear of the grill-retaining portion 33 which has a keeper 35. The face of the link 30 is divided. A cutout portion36 which has a hook 350 is provided as a part of the link 30 so that it will fit into the space provided for it as shown in Figure 10 of the drawings. I have also provided for a hasp 37 and a keeper 38 to provide means for locking the entire device by means of a padlock 39. A stop 43 is provided to keep the link 30 from moving sideways after it is in position.

The device as I have described it herein is used in conjunction with a double-hung type of window. I have shown in the drawings the window frame 12, the upper window frame 40 and the lower window frame 41. My device is used when both of the frames, lower 41 and upper 40, are in the raised position. The halves of the grill 15 are inserted into the side members 10 and 11. In the form of my invention disclosed herein, the left half 15a must be inserted first. I prefer to insert the left half 15a first by fitting the side piece 20 into the channel of the side member 10 and then sliding it down until the lugs 23 fit snugly into the holes 24 on the left side of the base portion 13. The top frame member 28 is inserted so that the solid block portion 28a fits into the channel of the side member 10 snugly against the solid end 10a and thereby prevents the left part of the grill 154: from being lifted and dislodged.

I then place the metallic link 30 under the lower portion of the raised lower window frame 41 and slide it over the centrally located end of the top frame member 23 so that the window frame receiving portion 31 will receive the window frame 41 and the grill retaining portion 33 will fit over the top frame member 28. The metallic link 30 is centered so that the center of the grill-retaining portion 33 is in registration with the inner edge of the top frame member 28. Thus, the stop 43 rests against the inner end of the top frame member 23. When the other top frame member 29 is placed in position, the stop 43 will be between both members 28 and 29 and will serve to prevent lateral motion of the link 30.

The right portion of the grill 15b is then placed in position in the same manner as the left-hand portion. The right-hand top frame member 29 is then placed in position with the solid block portion 29a within the channel of the side member 11. The cut-out portion 36 of the metallic link 30 is then placed in position by hooking the hook 35a inside the keeper 35. The hasp 37 is then placed over the keeper 38 and locked with the padlock 39. The grill 15 is removed by reversing the procedure.

It may be desired to keep the two halves of the grill 15a and 15 badjacent to the sides of the window 12 in open position. This may be done when the metallic link 30 and the top frame portions 28 and 29 are not on the device. The:lefthand.frame lsahis-inserted into the left sidemembenlflin theusual mannerliwith the exception .it is not slid down. The peg 2.7 is then inserted into the apertures 24 and 25. This retains the grill 15a in the open position. The other half of the g'rilllSb may be similarly retained in open position on the other side. a While I have described my device in its preferred'form, there are other forms in which it can be constructed Without departing from the claim of my invention and I desire to be protected for any form of construction'or equivalent which come'out of the claim following. 1

Wherefore, .I claim: V
